I think I've my problem solved. The 'Unlock' button worked if I just type 'users-admin' in the terminal, (without sudo or gksu in front of the command)
Then I checked my 'users-admin' launcher setting in the alacarte menu editor, the command was 'gksu users-admin', so I simply delete the 'gksu', and it worked properly without 'gksu' I guess it could be caused by my previous installation of 8.04 Release Candidate version, it left the old launcher setting in my home directory, so even I made a clean install of the formal 8.04 release later, the menu still uses the old setting (gksu users-admin) of my home directory. -- users-admin doesn't add admin users to lpadmin https://bugs.launchpad.net/bugs/152107 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
